RE: HP 82143A / HP 82162A foto coupler (encoder) - substitute
Dear Hans, looks very close to the original one. Starts with OPB as well. There are similar one's, OPB70.. I have to check the detective distance, 0.15 or 0.2 or 0.25 inch.
Maybe someone who is more familiar with transistors than me can tell the right one according to voltages. 25V or 30V collector emitter voltage? Or doesn't matter? Or need a Darlington version? For example: http://pdf1.alldatasheet.com/datasheet-p...asheet.pdf Thank the electronic experts for further help Andi |
